From: Richard Gong <richard.gong@xxxxxxxxx> Intel Stratix10 SoC is composed of a 64 bit quad-core ARM Cortex A53 hard processor system (HPS) and Secure Device Manager (SDM). When the FPGA is configured from HPS, there needs to be a way for HPS to notify SDM the location and size of the configuration data. Then SDM will get the configuration data from that location and perform the FPGA configuration. To meet the whole system security needs and support virtual machine requesting communication with SDM, only the secure world of software (EL3, Exception Layer 3) can interface with SDM. All software entities running on other exception layers must channel through the EL3 software whenever it needs service from SDM. Intel Stratix10 service layer driver, running at privileged exception level (EL1, Exception Layer 1), interfaces with the service providers and provides the services for FPGA configuration, QSPI, Crypto and warm reset. Service layer driver also manages secure monitor call (SMC) to communicate with secure monitor code running in EL3. This patch adds a device tree binding for Intel Stratix10 service layer driver Richard Gong (1): dt-bindings: misc: add Intel Stratix10 service layer binding .../devicetree/bindings/misc/intel-service.txt | 56 ++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 Documentation/devicetree/bindings/misc/intel-service.txt -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
